I think that news chip7 needs to have the compatibility with DDR3, and some more experience i think
Maybe its too soon to buy a new mobo like P5K and it doesn't support DDR3, only Asus P5K3 deluxe support it.

Its my opinion, if we want a new mobo, with support for the future we need to think about DDR3 and other technologies that could appear.
